Jim next door has Parkinson’s. They’ve suspected it for a while, Jim and Ann, and given his symptoms – asymmetrical pill-rolling style tremor; writing gone very small – I suspected it too. But they had to wait ages to see a neurologist and finally got confirmation last week.

Ann came round to tell me and asked how long it was since I’d been diagnosed. Just over four years, I told her, and tried to look jolly and bouncing with health. Which, actually, I am. Pretty much.
